Under active thyroid

[Ruelzdontapply]

Ds 2 had some blood test done. Today I received a letter with some of the results.

Child's thyroid function test were mildly abnormal for the 2nd time.
Repeat test 6 weeks to help decide if treatment needed.
Tsh: 7.82 miu/l
Throxine: 14.2 pol/l

Anyone have a child with a under active thyroid?
What is the treatment if needed?

It’s just levotnyroxine and regular blood tests

Thank you for you reply.
How regular are the blood tests he already has one every six months for something else and it's a bloody nightmare getting them done.

Daily medication half an hour to an hour before food. I have yearly bloods taken.
